Compact support for heavy radial loads

Practical benefits

Proven engineering by Skf: You benefit from a durable steel design built to withstand high radial forces across demanding mechanical applications.
Minimal cross sectional height: By mounting directly on a hardened shaft without an inner ring, you achieve an exceptionally space-saving assembly.
Simplified ongoing relubrication: The outer ring features a lubrication groove and holes, allowing you to easily maintain smooth rotation during operation.

In a nutshell

The right choise for

With the Skf nk 15/20 single row needle roller bearing, you achieve an exceptionally compact bearing arrangement that reliably handles heavy radial loads. Designed without an inner ring, it mounts directly onto a 15 mm hardened and ground shaft, saving critical space in gearboxes, industrial pumps, and mechanical drives. The machined 23 mm outer ring with integral flanges and a 20 mm width works together with a robust sheet steel cage to ensure precise roller guidance. Its open design features a lubrication groove and lubrication holes, making routine maintenance and relubrication quick and straightforward during demanding operations.
